[c-nsp] OSPFv3 support for IOS and IOS-XR

[Xu Hu]

Hi Folks,

Recently we are checking the OSPFv3 VRF support for IOS and IOS-XR.
Through the Cisco Feature Navigator, i found two related, one is MPLS VPN
OSPFv3 PE-CE, another one is OSPFv3 VRF-Lite/PE-CE, i don't know whether
this two are the same or not.
My understanding is that OSPFv3 VRF-Lite/PE-CE is for IOS, i.e, for the
7600.
Then the MPLS VPN OSPFv3 PE-CE is for IOS-XR, i.e, for the GSR, CRS,
ASR9000.

Will appreciate for any comments.

Thanks & Best Regards,
Hu Xu
